|---|---|
void |
close()
The close() method is called immediately before the Watch is destroyed, that is,
when the element whose declaration scopes the constraint implemented by this
Watch goes out of scope.
|
void |
endSelectedParentNode(int locationId)
Signal that the endElement event has occurred for the element whose startElement
event caused the Watch to be activated.
|
FleetingNode |
getAnchorNode()
Get the anchor node for the watch.
|
NamespaceResolver |
getNamespaceResolver()
Get the namespace resolver in use by the Watch
|
PipelineConfiguration |
getPipelineConfiguration()
Get the pipeline configuration in use
|
Pattern |
getSelection()
Get the selection (that is, the restricted XPath expression) that defines
the nodes that this Watch is looking for
|
void |
notifySelectedLeafNode(FleetingNode node,
int locationId)
Signal that a node (other than a document or element node) that matches the selection
has been found.
|
void |
open()
Open the watch.
|
void |
setAnchorNode(FleetingNode anchor)
Set the anchor node for the watch.
|
void |
setNamespaceResolver(NamespaceResolver resolver)
Set a NamespaceResolver for use by the Watch
|
void |
setPipelineConfiguration(PipelineConfiguration pipe)
Set the pipeline configuration in use
|
void |
setSelection(Pattern selection)
Set the selection (that is, the streamable XPath expression) that defines
the nodes that this Watch is looking for
|
Receiver |
startSelectedParentNode(FleetingNode node,
int locationId)
Signal that an element or document node has been found that matches the selection that this
Watch is looking for.
